Syntax

grGridlines(<Chart name> , <Display> , <Axis direction>)

<Chart name>: Control name or character string

Name of the chart to be used. This name corresponds to:
the chart name defined through programming with grCreate.
the name of the Chart control in the window, page or report editor.
Only Chart controls are available.
Only the interactive Chart controls are available.

<Display>: Boolean

True if the grid must be displayed,
False otherwise.

<Axis direction>: Integer constant (or combination of constants)

Axis used for the gridlines:
grXCoordinate
(default value) Marks on X-axis (horizontal axis).
grYCoordinate Marks on Y-axis (vertical axis).

The combination of these two constants is used to get a full gridlines (vertical and horizontal).

Remarks

The gridlines are taken into account:
- in Column charts (grColumn and grColumnStacked constants), Scatter charts (grScatter constant), Line charts (grLine constant) and Stock charts (grCandleStick, grBarCharts and grMinMax constants) when <Axis direction> corresponds to grXCoordinate.
- in Scatter charts (grScatter constant), Line charts (grLine constant) and Stock charts (grCandleStick and grBarCharts constants) when <Axis direction> corresponds to grYCoordinate.
The gridlines have no effect on Pie charts (grPie constant) and Funnel charts (grFunnel constant).
The data defined by grGridlines will be taken into account during the next call to grDraw.
